The Do’s and Don’ts of VoIP Phone System Security


A phone system that uses voice over internet protocol delivers voice and multimedia communications via an internet connection. This technology can streamline your business operations, ensure quality calls, and keep staff members connected, no matter their location, to name just a few benefits. But because VoIP phone systems relay data over internet networks, it’s important to implement some security measures. Here are some dos and don’ts for maximizing your VoIP security.


Use a firewall.

At its most basic, a VoIP phone system is simply a telephone connected to an ethernet or a wi-fi network. And like any other electronic item plugged into the internet, it needs to have a secure firewall. Without a firewall, your data is much more exposed and is at greater risk of hacking and theft. Consult your VoIP service provider about the most effective firewall solutions for your business’s needs.

Keep track of usage.

When a hacker accesses a VoIP system, they will typically try to make calls that end up being charged to the business. The actual performance of the system may be largely unaffected, so the only way to tell if you’ve been hacked is by reviewing call records. Get in the habit of checking all call logs. If your provider charges for outbound calls, be sure to check your phone bills each month as well.


Grant the same permissions to all employees.

Not every staff member needs the same security permissions, and one of the great benefits of VoIP technology is that it lets you pick and choose the accessibilities and capabilities of each user. Review your staff list carefully and only give the permissions that each individual needs to perform their job. For example, if someone only handles regional sales, they likely don’t need to make international calls. Limiting their permission to domestic calls will keep costs low and minimize potential security breaches.

Mix LANs.

Many businesses use both handsets and cloud-based interfaces. This results in a combination of mobile apps, desk phones, softphones, printers, and other components all connected to the same VoIP network. But you shouldn’t mix form factors and connected devices within the same network structure. Instead, have your provider set up a private VLAN, a dedicated virtual local area network. This allows for better management and security, since it directs VoIP traffic onto its own network, improving safety in the process.
